I just purchased the generator and the set up was very simple. I connected the battery, added gas and the included oil then turned on the fuel switch and battery toggle and then pressed start and it started immediately. I am in the process of the 5hr. Break in period utilizing varying loads up to 50% of maximum.
I bought this to power my 30-amp camper when the AC is running. It fully powers the whole camper electrics - even better than city electricity because it doesn't fluctuate much in voltage (although I still use the voltage regulator like I do at a camp site). The control panel is easy to learn, easy to use. I really like the "ready" light which tells me when to power up the camper. I load/unload it from my truck bed via a ramp. The "suitcase" handle" makes it way easy to tote around.
